Enable Disconnection
This option determines whether the SCSI controller allows a SCSI
device to disconnect from the SCSI bus (sometimes called
Disconnect/Reconnect).
Disconnect/Reconnect allows the SCSI
controller to perform other operations on the SCSI bus while the SCSI
device is temporarily disconnected.
When set to
Yes
, the SCSI device may disconnect from the SCSI
bus. The SCSI device, however, may choose not to disconnect, even
if permitted by the SCSI controller. When set to
No
, the SCSI device
is not allowed to disconnect from the SCSI bus. The default setting is
Yes
.
Keep this item set to
if two or more SCSI devices are connected
Yes
to the SCI controller. This optimizes SCSI bus performance. If only
one SCSI device is connected to the SCSI controller, set this item to
to achieve better system performance.
No
Initiate Wide Negotiation
This option allows communication between all devices (lower 8-bit or
upper 8-bit) on the wide (16-bit) SCSI bus. When set to
Yes
, each
device can connect on the bus.
When set to
(disabled),
No
communication can only occur on the lower eight bits of the 16-bit
SCSI bus. The default setting is
Yes
.
Send Start Unit Command
This option determines whether the Start Unit Command (SCSI
command 1B) is sent to the SCSI device (most devices do not require
this). Enabling this item reduces the load on the system power supply
by allowing the SCSI controller to power-up SCSI devices one at a
time upon booting. Otherwise, all the devices power up at the same
time.
Most devices require you to set a jumper before they can
respond to this command.
